Ortlepp, R.J.; DuToit, P.J.
(Pretoria : The Government Printer, 1940)
In the foregoing the writer discusses five species of Cestodes and one species of Nematode; of the cestodes three species are considered as new and the species from the Hoepoe is assigned to a new genus Biuterinoides closely ...

1. It is believed that various outbreaks of swine fever in South
Africa have probably occurred since 1900. The disease in domestic pigs produced by the blood of warthogs resembled the European disease. Probably in swine ...

(Pretoria : The Government Printer, 1940)
An apparently new form of conjunctivitis of the domestic fow1 has been described. No doubt the disease has been seen before and called “ocular roup”.
The condition is confined to the structures of the eye. Transmission ...

(Pretoria : The Government Printer, 1940)
Cystine is determined as cysteine in hydrolysates of plant or
biological material of low cystine content. This method is an improvement and also more accurate than the previous one described.

Roets, G.C.S.; DuToit, P.J.
(Pretoria : The Government Printer, 1940)
A spectroscopic method for the quantitative determination of the

into pyridine haemochromogen and a comparison of the intensity of
the 555 absorption ...

From a study on the dry matter consumption of sheep under
natural conditions of grazing, it is evident that the quantity consumed
is not a factor in the loss of weight in sheep during winter.
It appears from these ...

By means of paired feeding tests, it has been shown that sesamemeal is deficient in cystine and that cottonseedmeal is not deficient in this amino acid. Bran and coprameal are apparently not deficient in lysine, while the ...
